A TECHNICAL REVIEW OF PEAK TO AVERAGE POWER RATIO REDUCTION IN MIMO - OFDM

In this paper, detailed review of bit error rate (BER) and peak to average power ratio (PAPR) reduction in multiple input multiple output - orthogonal frequency division multiplexing (MIMO - OFDM) and performance analysis of OFDM in various channel is given. This paper will contribut e in better choices of technical methods to reduce bit error rate and the peak to average power ratio in orthogonal frequency division multiplexing for high speed wireless communication. One major shortcoming of OFDM is the high peak - to average Power ratio (PAPR). Most investigated techniques modified are Selected Mapping (SLM) and Companding scheme (CS).These are PAPR reduction techniques for multiple input multiple output - orthogonal frequency division multiplexing (MIMO - OFDM) without affecting the Bandwid th proficiency of the system and the Bit Error Rate (BER) performance. This is one of the strongest candidates for Future 5 - G LTE wireless communication.
